Description

Technical Field

[0001] This utility model belongs to the field of shell structure technology, and relates to a shell structure for multiple batteries connected in parallel in electric vehicles. Background Technology

[0002] In recent years, with the rise of the new energy industry and the growing consumer base, users are paying increasing attention to battery safety. Battery manufacturers have designed various structures to secure battery installation. These designs typically use fasteners to mount the battery to the battery casing, preventing displacement between the battery and the casing and thus avoiding collisions. The battery casing usually consists of two parts: a housing and a cover. The housing has a groove where the battery is secured with fasteners, and the cover seals the groove. Because the battery is only connected to the housing, the stress at the connection point is high when the battery casing is impacted, which can easily lead to battery breakage and safety accidents. Therefore, this paper proposes a casing structure for multiple batteries connected in parallel in electric vehicles to address the above problems. Utility Model Content

A buffer bottom block 6 is provided inside the upper part of the base 3.

[0026] Multiple upper clips 102 are provided around the top of the main protective shell 1, and the multiple upper clips 102 equally divide the top of the main protective shell 1. Multiple upper plug-in parts 202 are fixedly connected to the bottom of the upper cover 2, and the multiple upper plug-in parts 202 equally divide the bottom of the upper cover 2. At the same time, the upper plug-in parts 202 are inserted into the fixedly connected upper clips 102, and the bottom of the upper cover 2 is tightly fitted to the top of the main protective shell 1.

[0027] An upper locking part 102 is provided above the main protective shell 1, and an upper plug-in part 202 is provided below the upper cover 2. They cooperate with each other. After the upper cover 2 is pressed onto the main protective shell 1, the upper locking part 102 and the upper plug-in part 202 engage, making the upper cover 2 and the main protective shell 1 a whole. At the same time, the two are sealed together, making disassembly convenient. In addition, a gasket is installed at the seal to buffer collisions.

[0028] Furthermore, the top of the upper cover 2 is provided with an arc-shaped groove 204, and the two ends of the handle strip 201 are fixedly connected to the two sides of the arc-shaped groove 204 respectively. There is a distance between the lower part of the middle of the handle strip 201 and the bottom of the arc-shaped groove 204, and the upper part of the middle of the handle strip 201 extends beyond the top of the upper cover 2.

[0029] A handle 201 is provided above the top cover 2. The entire outer shell structure, including the internal battery, can be lifted using the handle 201 for easy movement.

[0030] Furthermore, a positioning block 4 is fixedly connected to one corner of the upper cover 2, and the electrical connector 5 is inserted into the lower part of the fixed connection within the positioning block 4. At the same time, the horizontal section of the electrical connector 5 is positioned above the top of the upper cover 2, and the lower part of the electrical connector 5 is connected to the internal battery.

[0031] Furthermore, a display adjustment component 7 is fixedly connected to the other corner of the upper cover 2, and an internal battery is connected below the display adjustment component 7. At the same time, an adjustable button and multiple indicator lights are provided above the display adjustment component 7.

[0032] An electrical connector 5 and a display adjustment component 7 are respectively provided on the top of the cover 2. The electrical connector 5 is a bridge connecting the internal battery and the external working element. The battery power is supplied to the outside through the electrical connector 5, while the display adjustment component 7 is used to adjust and observe the power of the internal battery.

[0033] Multiple lower clamping parts 103 are provided below the main protective shell 1, and the multiple lower clamping parts 103 equally divide the lower circumference of the main protective shell 1. Multiple lower plug-in parts 303 are fixedly connected above the base part 3, and the multiple lower plug-in parts 303 equally divide the upper circumference of the base part 3.

[0034] Furthermore, the lower plug-in part 303 is inserted into the fixed connection lower clip part 103 above, and the bottom of the main protective shell 1 is tightly fitted with the top of the base part 3.

[0035] After the lower clip part 103 located below the main protective shell 1 and the lower plug part 303 located above the base part 3 cooperate with each other, the main protective shell 1 and the base part 3 form an integral unit. In this way, the main protective shell 1, the upper cover part 2 and the base part 3 form a complete outer shell structure. At the same time, a gasket is also provided at the sealing point between the main protective shell 1 and the base part 3 to protect the internal battery and prevent collisions.

[0037] Furthermore, the bottom of the battery is inserted into the battery mounting groove 301, and the top of the battery is placed in the battery placement part 101, while the top of the battery is tightly fitted to the bottom of the upper cover 2.

[0038] After the battery placement part 101 inside the main protective shell 1 is engaged with the battery mounting groove part 301 above the base part 3, the battery is placed from the top of the main protective shell 1 into the interior, so that the parallel battery pack is protected by the main protective shell 1, the top cover part 2 and the base part 3.

[0039] The base component 3 has multiple grooves 302 at its bottom, and a buffer block 6 is inserted and fixedly connected into the grooves 302. At the same time, the bottom of the buffer block 6 is lower than the bottom of the base component 3.

[0040] The base component 3 has a buffer block 6 at the bottom, which buffers the entire shell structure from below. When the shell structure is placed vertically, the buffer block 6 increases friction and support.

[0041] Working principle:

[0042] After the upper locking part 102 provided above the main protective shell 1 and the upper plug-in part 202 provided below the upper cover 2 are inserted into each other, the main protective shell 1 and the upper cover 2 become one unit. After the lower locking part 103 provided below the main protective shell 1 and the lower plug-in part 303 provided above the base part 3 are inserted into each other, the main protective shell 1 and the base part 3 become one unit. The battery pack is placed inside from the top opening of the main protective shell 1, so that the battery pack slides down along the battery placement part 101 inside the main protective shell 1 and the bottom of the battery pack is placed in the battery mounting groove part 301 above the base part 3. In this way, the battery pack is installed in the entire shell structure. Then the upper cover 2 is pressed closed, so that the entire shell structure protects the parallel battery pack.
